feat: add oxfmt support

[haoqunjiang]

Closes #93

Note:

As Oxfmt doesn't support languages other than TS and JS, we still need prettier. And in VS Code, we need the following to be added to .vscode/settings.json:

  "oxc.fmt.experimental": true,
  "[javascript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode"
  },
  "[javascriptreact]": {
    "editor.defaultFormatter": "oxc.oxc-vscode"
  },
  "[typescript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode"
  },
  "[typescriptreact]": {
    "editor.defaultFormatter": "oxc.oxc-vscode"
  }
